MSP430F5659: Firmware update using USB connection with Human Interface Device protocol

user4198614

Part Number: MSP430F5659
Other Parts Discussed in Thread: MSP430USBDEVPACK, MSP430WARE, MSPBSL

Hi,

I am trying to build a cross platform command line USB tool (in Rust) to control a device which is equipped with a MSP430F5659 chip. This tool will help my organization by allowing people to request things from the device.

Now I would like to add a new feature to this tool. I would like to be able to flash the firmware. The communication between the computer and the external device is based on the Human Interface Device protocol and I would like to keep using it.

I did not find any resources about it. Can you guys tell me if this is possible and where can I find informations about that ?

Hi,

The MSP430 USB BSL uses a HID protocol to accomplish firmware updates. I recommend you read through Section 1.5 of the BSL User's Guide (SLAU319) and refer to the USB Field Firmware Updates App Report (SLAA452). A python-based firmware upgrader example is also provided in the MSP430USBDEVPACK resources.

Ryan

Hi,

We are also working on same thing Creating a custom USB BSL for msp430F5659 for firmware upgrade.
The BSL source code can be found at C:\ti\ccsv5\ccs_base\msp430\msp430ware_1_40_01_44\boot_loader\Customizing_the_BSL
Unzip it and see USB examples.
You have to change the project /linker file according to your mcu.
The default value of crystal supported are 4,8,12,24 mhz but for this mcu 20mhz is max frequency so default crystal will be 4,8,12 mhz. If you plan to use any other value you should edit in the source file to customize your BSL.
The source file is in IAR format , you can easily edit it for customization according to your need and rebuild it.
We are even working on same thing with 20mhz crystal and don't want to use IAR for the same so we are working to figure out how to proceed with CCS to do the same customization.
Let me know if you find any further information about it so that we can discuss further and both will be mutually benefited.

Regards
Yousuf

The file path you gave me is incorrect because it is only available on your machine. Can you provide me a web link ?

The MSPWare version Yousuf is referring to is quite old anyways, you should download the most current version from the software downloads page. The boot_loader folder referred to still exists in the newer revisions.

Are you sure ? I did not find any boot_loader folder in the resource I downloaded

TI__Guru**** 220847 points

Well the boot_folder is still inside of the new MSP430Ware downloads but only point to the CUSTOM-BSL430 software package which is provided on the MSPBSL tools page. You will also do well to look at the python firmware updater example from MSP430USBDEVPACK.

Ryan

Yeah I am trying to analyze the python example but it is kind of tricky to transpose all of that to my Rust tool. Have to first understand the sequence of calls then look at the low level HID calls to understand what bytes I have to send. I wish I had a simple HID procedure/documentation.

This is detailed in Section 3 of SLAU319.

I have been looking at the BSL USB GUI.sln project using VisualStudio. It is pretty simple to understand but I was wondering if there was a way for me to access to the implementation of the functions starting with the BSL prefix like BSL_LoadPC_l() ?

I cannot comment on what is possible given my limited experience with this Visual Studio project.

I have already downloaded this resource but I can't see the code I was talking about. Yesterday I found this project github.com/.../InnovasubBSL430 which I am going to "translate" to my Rust tool.

I am still not clear regarding what you are looking for..
1- You want the BSL source code for msp430f5659 for customizing the BSL ??
2-You want the host application source code which is used to program the mcu from PC ??

Hello Yousuf,

Just a quick message to tell you that I have been able to create the tool I was talking about last time.

Here is my code: gist.github.com/.../c9b708a72d831c2a3a65457af3dd7ed8

Thanks to all of you for your help !
